Question

Researchers recorded that a group of bacteria grew from 30 to 900 in 18 hours. At this rate of growth, how many bacteria will there be in 36 hours from the start of the experiment? Round to the nearest whole number.

Answer 1

At this rate of growth, researchers can expect 27,000 bacteria.

Explanation:

Answer 2

The will be 27000 bacteria in 36 hours from the start of the experiment

Explanation:

In the first 18 hours:

The number of bacteria grew from 30 to 900.

So it grew by a factor of 900/30 = 30.

36 hours from the start of the experiment:

That is, the next 18 hours.

It will also grow by a factor of 30.

From 900 to 900*30 = 27000

The will be 27000 bacteria in 36 hours from the start of the experiment
